ZALACCA (said to be the name of this genus in the 
Moluccas). Sometimes spelt Salacca. ORD. Palme. A 
genus comprising about eight species of stemless, stove 
Palms, with soboliferous roots; one is a native of Assam, 
and the rest inhabit the Malayan Archipelago. Flowers 
often pink, polygamo-monecious or dicwcious; spathes 
persistent, the lower ones sheathing the peduncle and 
branches, incomplete, the partial ones subtending the 
floriferous branchlets; spadices simple or fastigiately 
branched, pendulous, the floriferous branchlets catkin- 
like, rather short, remote or clustered, sessile or pedun- 
culate ; bracteoles connate in a. two-celled cup. Fruit 
globose, turbinate, or ovoid, one to three-seeded, usually 
beaked. Leaves elongated, equally pinnatisect; segments 
alternate, fastigiate or equidistant, lanceolate or ob- 
lanceolate, straight or falcate, acuminate ; rachis obtusely 
triangular, not produced into a spine; petioles slightly | 
terete, armed with often spirally-disposed prickles. The 
best-known species are here described. The plants grown 
in some nurseries under the names of Z. nitida and 
Z. Wagneri perhaps represent distinct species, but so 
little is known about them that they cannot be described. 
The cultural directions given under Cycas are applicable 
to this genus. 
Z. Blumeana (Blume’s). A synonym of Z. edulis.

males axillary, longer Pi more biaha than the females ; 
female catkins 2in. to Ain. long, thicker than the males. fr. ful- 
vous-fuscescent, pyriform, 2}in. long. I. copious, clustered, erect, 
clothed with long, often serrate prickles ; pinnæ linear-lanceolate, 
very long-acuminate, 14ft. to 2}ft. long, ljin. to 2in. broad, 
whitish beneath; petiole rather shorter than the rachis, and 
armed with robust prickles. Malay Archipelago, 1847. Syn. 
Z. Blumeana. 
Z. Wallichiana (Wallich's) fl., spadix 
drooping or pendulous, long-branched ; 
long, the female ones cylindrical, 2in. GE Jr. ovate-pyriform, 
lyin. long, slightly acute. J. 18ft. to 20ft. long, clustered, nearly 
erect ; pinnæ fascicled in twos, threes, or fours, narrow-lan- 
ceolate, with a long and slender, cuspidate point, attenuated and 
reduplicate at base, flat, the older ones lift. long, Ain, to 4in. 
broad ; petiole 4ft. to 6ft. long, armed with robust, us 
prickles. India, &c., 1847. (G. C. 1873, p. 1803.) 
ZALUZANIA (named after Adam Zaluziansky à 
Zaluzian, a physician of Prague, who published “ Methodus 
Herbarie" in 1602). Including Chiliophyllum and Fer- 
dinanda (in part). ORD. Composite. A genus embracing | 
seven species of stove, greenhouse or half-hardy, Mexican | 
shrubs or under-shrubs. Flower-heads yellow (or white), |

axillary, many feet long, 
male catkins lin. to 2in. 
radiate, sometimes rather small, in leafy, 
corymbose panicles. Ferdinanda eminens is a tall, stove 
shrub. Flower-heads white, small, disposed in an ample 
panicle; involucre short, the narrow bracts in two or 
three series. Leaves opposite, petiolate, large, angular- 
lobed. Podachenium paniculatum is now the correct 
name of this plant. It thrives in a compost of loam 
and peat, and may be increased by cuttings, inserted in 
sand, under a glass, in heat. : 
ZALUZIANSKIA (named in honour of the “saq 
person as the precedin nus). Syn. Nycterinia. ORD.

Species of more or less viscous, greenhouse or half-hardy. 
South African, annual or perennial herbs or sub-shrubs. 
Flowers sessile, spicate; calyx shortly five-toothed, bi- 
labiate or two-parted; corolla persistent, at length cleft 
to the base, the limb of five spreading, entire or bifid 
lobes; stamens often four. Lower leaves alternate; upper | 
ones opposite, few-toothed ; floral ones bract-like, entire — 
Three species have been introduced. All thrive in a | 
mixture of sandy loam and peat. Seeds of 8. capensis 
and 8. nor s may be sown, in summer, in the open 
ps ved . 8. lychnidea may be increased by cuttings, or by 
Zaluzianskia—continued.
